which we can identify as the Reuter fixed point [1]}, [2]}.
The Reuter fixed point splits the phase diagram of quantum gravity into a weakly coupled and strongly coupled regions for \(0<\tilde{G} < \tilde{G}_{\star }\)  and \(\tilde{G} > \tilde{G}_{\star }\) , respectively.
The critical exponent at the Reuter fixed point
\(= - \frac{\partial \beta _{\tilde{G}}}{\partial \tilde{G}}(\tilde{G}_\star )\)
